First light with the 2nd hand NEQ6 mount: Algol, the Demon Star

This is the first testshot I made with the 2nd hand NEQ6 I bought a few weeks ago. It is a single frame shot of 30sec exposure at ISO800 with the Eos400d in primary focus of the 200mm Newtonian telescope. The guiding is very tight. I need to focus on collimation because that is clearly visible on this picure. The MPCC could not compensate all.
The datalogging of the autoguiding shows a much smoother running on the RA axis (the undershoot is when I touched the cam between exposures). Next step is focus on driftalignment and reducing coma.
